DURABLE. STABLE. RELIABLE.
TUF GAMING B550-PRO distills essential elements of the latest AMD platform and combines them with game-ready features and proven durability. Engineered with military-grade components, an upgraded power solution and a comprehensive set of cooling options, this motherboard delivers rock-solid performance with unwavering gaming stability.

When you build with a TUF Gaming motherboard, you also benefit from the TUF Gaming Alliance — an ASUS collaboration with trusted industry partners that ensures easier building, best compatibility, and complementary aesthetics from components to case.

ROCK-SOLID PERFORMANCE
With upgraded power delivery and comprehensive cooling options to fuel the latest AMD Ryzen CPUs, plus support for faster memory and storage, TUF Gaming B550-PRO is the perfect foundation for your next high-core-count battle rig.

Power Design
DrMOS
The onboard VRM of TUF Gaming B550-PRO utilizes 12+2 DrMOS power stages that combine high-side and low-side MOSFETs and drivers into a single package, delivering the power and efficiency that AMD Ryzen™ 5000 Series/ 4000 G-Series/ 3000 Series Processors demand.

Stack Cool 3+
2-ounce copper layers draw heat away from critical components to keep them at their optimal operating temperatures and provide more headroom to push CPUs beyond stock speeds.

ProCool Socket
ENHANCED 8-PIN + 4-PIN CONNETOR
- Extreme durability
- Prevent hotspots and connector failure

Compared with traditional power inputs, ProCool sockets are built to tight specifications to ensure flush contact with PSU power lines. The resulting lower impedance helps to prevent hotspots and connector failure.

TUF COMPONENTS
TUF CHOKES
Certified military-grade TUF chokes deliver rock-steady power to the CPU, improving system stability.

TUF CAPACITORS
Proprietary capacitors provide up to 20% greater temperature tolerance and 5X-longer lifespan.

Digi+ VRM
The integrated Digi+ VRM voltage-regulator module (VRM) is one of the finest in the industry, ensuring ultra-smooth and ultra-clean power delivery to the CPU at all times.

EASY PC DIY
TUF Gaming motherboards are designed to be easy to set up and configure just the way you want — even for first-time builders. The TUF Gaming Alliance ecosystem makes selecting compatible parts easy, while Armoury Crate software offers full control of system settings via a single dashboard. TUF Gaming motherboards give you everything you need to build your dream gaming rig without adding complexity.

Build with confidence
TUF Gaming Alliance is a collaboration between ASUS and trusted PC-component brands to ensure compatibility with a wide range of parts, such as PC cases, power supplies, CPU coolers, memory kits and more. With more partnerships and components being added regularly, the TUF Gaming Alliance will continue to grow even stronger.

SafeSlot
SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured via a new insert-molding process, SafeSlot integrates fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.

ESD guards
ESD Guards prolong the life of components while preventing damage from electrostatic discharge, providing protection for up to +/- 10 kV of air discharge and +/- 6 kV of contact discharge — greatly surpassing the respective industry standards of +/- 6 kV and +/- 4 kV.

TUF LANGuard
TUF LANGuard is a military-grade innovation that integrates advanced signal-coupling technology and premium surface-mounted capacitors to improve throughput, protecting the motherboard from lightning strikes and static electricity.

DRAM overvoltage protection
Onboard resettable fuses prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to safeguard the lifespan of your system and connected devices.

Stainless-steel back I/O panel
TUF Gaming motherboards have a corrosion-resistant stainless-steel back I/O panel bonded with chromium oxide to provide a 3X-longer lifespan versus traditional panels. With this protective feature, TUF Gaming motherboards passed 72-hour salt fog testing, while other brands only passed 24-hour testing.

IMMERSIVE GAMING
TUF Gaming B550-PRO provides a complete, high-performance gaming package with a long list of features to improve your experience, including ultrafast networking for smoother online gameplay, pristine audio with positional cues for FPS gaming, and onboard RGB lighting that syncs with attached accessories to help you create a personalized gaming atmosphere.

EXCLUSIVE 2.5 GIGABIT ETHERNET
2.5G on-board Ethernet kicks your LAN connection up a notch with an up to 2.5X bandwidth improvement. Using your existing LAN cable, you can take advantage this networking upgrade to experience smoother, lag-free gaming, immediately stream high-resolution videos and enjoy faster file transfers.

Turbo LAN
NETWORK-OPTIMIZATION SOFTWARE FOR CUSTOMIZABLE PACKET PRIORITIZATION
Turbo LAN is a network-optimization software for customizable packet prioritization. With cFosSpeed traffic-shaping technology, it allows you to configure application priority via an intuitive interface, and reduces network lag.

1. ONE CLICK TURBO
